[bsp][wch][risc-v] add drv_flash for ch32v307. (#10306)

* [bsp][wch][risc-v] add drv_flash for ch32v307.

* [bsp][wch][risc-v] 1. add yml file for ch32v307.
                   2. fix programs a word at chip flash timeout.
                   3. priority use of fast mode.

* [bsp][wch][risc-v] fix spi device for ch32v307.
